Command Remarks
3. Configure one or more
destination addresses and
dial strings that can be
auto-dialed.
dialer number dial-number autodial
dialer route ip next-hop-address [ mask
network-mask-length ] [ vpn-instance
vpn-instance-name ] dial-number [ autodial
| interface interface-type
interface-number ] * [ broadcast ]
By default, auto-dial is
disabled.
To configure an interface to
place calls to a single site,
use the dialer number or
dialer route command to
specify the dial string used
to reach the site. To
configure an interface to
place calls to multiple sites,
use the dialer route
command multiple times to
specify the dial strings and
destination addresses to
reach the multiple sites.
4. (Optional.) Set the auto-dial
interval.
dialer timer autodial seconds
The default setting is 300
seconds.
Configuring circular dial string backup
Auto-dial can be used only with C-DDR. With C-DDR, you can configure multiple dialer route commands
for the dial strings used to call a destination address. These dial strings are backups to each other. If DDR
fails to call the remote end with a dial string, it will select the dialer route command with the next dial
string for another try.
To configure circular dial string backup:

interface) view.

3. Repeat this step to associate multiple dial
strings with the same next-hop-address.

Configuring attribute parameters on a dialup
interface
C-DDR and B-DDR are available with some optional parameters. Configure them appropriately to
improve on-demand dial efficiency.
You can configure the following parameters on a dialup interface:
• Link idle-timeout timer—A link idle-timeout timer starts upon setup of a link. When the timer expires,
DDR disconnects the link.
